I don't know how well the drivetrain would swap over between generations. I've seen an EVO V and an EVO VII swap with the whole AWD system ported over, but only for same-model cars. You'll need a full front-clip and a cut-out rear subframe with the mounts for the rear-differential on top of all the drivetrain hardware.
EDIT: I can't vouch for the safety of cutting out the rear multi-link mounting brackets and replacing them... this is basically a do-it-at-your-own-risk conversion!
Commonly, these swaps are also done with the doors, front fenders, bodykit, bumpers, hood, wheels, brakes, seats, etc... of the EVO, with only the pillars, roof and floorpan remaining stock... The whole shebang (for an EVO VI) costs around $10k here (likely cost more due to importation there), don't know how much it'll cost for an EVO VII to VIII (same body as the ES), but it may cost a lot less without the aluminum body panelling...
If it's legal to do this swap with the drivetrain in your state (not likely if you're from Cali...

), and you're willing to take the risk, hey, go for it. It will be hella fast, and the only problem will be that the chassis will not be quite as stiff as an EVO chassis, and you'll still have to flare the fenders to fit the wider track if you don't get the body panelling from the EVO.
I often wonder if it will work for the Mirage, as that's basically a two-door Lancer and was sold here side-by-side with the four-door model with the same drivetrains and engines... but I'm not sure if the wheelbases are the same... would be nice... but they often just do the V6 MIVEC (FTO) swap for those... which is supposed to be a pain in the ass because of the wiring.
